Q

Diabetics with poor glycaemic control have a _____ fold increased risk of developing periodontitis

A

three fold increased risk of developing periodontitis

20
Q

What test can give an indication of long term glycaemic control?

21
Q

What kinds of periodontitis patients are at a risk of developing diabetes?

A

those with higher levels of HbA1c

22
Q

Patients with T2DM with periodontitis are more likely to experience diabetic complications. True or false

23
Q

What factors contribute to the risk of developing periodontitis in diabetic patients?

A
  • PMNL functions
  • Collagen metabolism
  • Advanced glycation end-products
24
Q

How is PMNL function affected in diabetes?

A
  • impaired chemotaxis, phagocytosis and adherence
  • PMNL defects may be inherited or secondary to hyperglycaemia
25
How is collagen metabolism affected in patients with diabetes?
diabetics synthesis less collagen diabetics also have higher levels of PMNL collagenase which breaks down collagen ## Footnote smoking affects fibroblasts; collagenase also affected in smoking
26
Outline the impact of AGE products in the pathogenesis of periodontitis in diabetic patients
* in hyperglycaemic environments AGE formation increases * AGE produces cause collagen cross linking (covalent bonds between collagen and other fibrils)- reducing solubility/turnover of collagen * reducing solubility/turnover of collagen means that there is impaired wound healing * monocytes also have receptors for AGE- RAGE (receptors)- when AGE binds to RAGE, release of pro-inflammatory cytokines such as IL-1, IL-6 and TNFa are released * would healing ( due to compromised collaged solubility and increased collagenase removal of newly formed collagen) compromised
27
How do you manage periodontitis in diabetic patients?
* advise patient about increased risk of periodontal disease * collect detailed diabetic history * review MH * maintain periodontal health *advice * tailored OHI * diet advice * smoking cessation if applicable * PMPR as indicated
28
Briefly outline the association between the glucose metabolism and the changes to the periodontal microbiome
* recent studies show an association with altered glucose metabplism and periodontal microbiomer * no causal relationship has been developed
29
Improving control of diabetes can result in improvements in periodontal status. True or false
true
30
Improving periodontal health can result in the improvement of metabolic control and/or complications of diabetes. True or false
true
31
Atherosclerotic cardiovascular diseases (ACVDs) include …
* coronary heart disease- MI, angina * ischaemic cerebrovascular disease- stroke, TIA * peripheral vascular disease
32
Periodontitis is a chronic inflammatory condition, if left untreated it can result in…
exarcebation of inflammatory conditions including ACVDs
33
Outline a plausible mechanism for the periodontal relationship with CVD
* chronic oral infection --> bacteraemia --> host response/inflammation --> athero-thrombotic lesion
34
There is _______ evidence base that CVD is a risk factor for periodontitis
limited thought is was strong?
35
What kind of treatment can induce bacteraemia?
periodontal treatment
36
CRP is used to measure …
inflammation good measure for future ACVD as higher levels of CRP are associated with increased risk of cardiovascula events
37
How should you manage periodontitis with patients who have CVD?
* staged periodontitis treatment * multiple visitis area advised * liaise with cardiologist * patienst with perio and other risk factors such as HTN, smoking or obesity who have not seen their GMP for over a year should book a cardiac review
38
Why are multiple visits advised for perio patients with CVD?
treatment is associated with transient impairement of endothelial function a week after
39
What is the recall for periodontal monitoring for patients with CVD with no periodontitis?
regular periodontal monitoring at least every 12 months
40
Poor diet/nutrition is a _______ variable for the development of periodontitis
confounding
41
There is currently no proven link between osteoporosis and periodontitis. True or false
true
42
What is the current evidence for links between rheumatoid arthritis and periodontitis?
some evidence that periodontitis may contribute to pathogenesis of RA however longitudinal study required to clarify association
43
What is an important factor for the prevention of hospital acquired pneumonia, especially in patients on ventilators?
improved oral hygiene
44
What are the difficulties with establishing associations/links between CKD and periodontitis
* complex pathogenesis * links with diabetes and other conditions
45
Recent meta-analyses consistently show a ________ association between obesity and periodontitis
statisitically significant positive however few studies included are longitudinal thus overall effect appears to be modest
46
Why are studies into possible associations between periodontitis and cancer difficult?
* unable to control confounding factors such as smoking and socio-economic status
47
Periodontitis has been identified as a possible risk factor for what kinds of cancers? (further long- term follow up studies are still needed)
pancreatic cancers oro-digestive cancers
